Correct S3 Bucket Architecture for Microservices

Question

I am building a microservices web application. I want to know the correct S3 structure for storing my data. The web application will have a couple of unrelated microservices and will be used by thousands of users. I don't know if all data should be stored under one single bucket in the format: `arn:aws:s3:::my-bucket/service-N/user-M/*` or have a bucket for each microservice and a folder for each user: `arn:aws:s3:::service-N-bucket/user-M/*`.  My intuition is to go for the second option since its more decoupled. Is there any best practice regarding this matter?

Answer

Hi,

You could read Best practices design patterns: optimizing Amazon S3 performance before creating your structure additionally I could suggest you to read Organizing objects using prefixes, Performance Guidelines for Amazon S3 and Performance Design Patterns for Amazon S3.

All those information will help you to define your prefix structure to save your data into s3.
